Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method for transmitting data, a communication device, and a network device. Background Art

[0002] Random access is a basic and important process in Long Term Evolution (LTE) and New Radio (NR) systems. Its main purposes are as follows: 1. Establish uplink synchronization; 2. Allocate a unique Cell Radio Network Temporary Identifier (C-RNTI) to the terminal and request the network to allocate uplink resources to the terminal. Therefore, random access is not only used for initial access, but also for new cell access during handover, access after radio link failure, re-establishing uplink synchronization when there is uplink / downlink data transmission, and uplink shared channel (UL-SCH) resource requests. After completing the random access process, the terminal can enter the connected state and establish a Radio Resource Control (RRC) connection with the base station to transmit data with the network.

[0003] In many application scenarios, there may be some data packets with a size smaller than a preset threshold that need to be sent. In the prior art, in order to reduce signaling overhead and save terminal power consumption, an early data transmission (EDT) mechanism is proposed. A terminal in an idle state can perform uplink data transmission once during the random access process, or configure a pre-configured uplink resource (PUR) for the terminal when the last RRC connection is released, and then use the PUR to transmit such data packets. However, in both cases, the terminal can only perform uplink data transmission once, and only when the size of the data to be transmitted on the terminal side is less than or equal to the maximum data block (Transport Block Size, TBS) size of EDT or PUR can EDT or PUR be used for transmission. Otherwise, the terminal must first enter the connected state through the RRC connection recovery process before sending the data to be transmitted. Summary of the Invention

[0004] The technical problem to be solved by the embodiments of the present application is to provide a method, a communication device and a network device for transmitting data, so as to solve the problem of large signaling interaction overhead and high terminal power consumption when a terminal transmits multiple data packets in an inactive state.

[0005] In a first aspect, an embodiment of the present application provides a method for transmitting data, including:

[0006] The terminal sends an instruction to the network device, the instruction information being used to instruct the terminal to send transmission information of one or more data packets when in an inactive state; the terminal sends the one or more data packets. Using embodiments of the present application, the terminal can inform the network side of its own transmission information when in an inactive state, which facilitates the network side's control of the terminal's transmission state and related resource allocation, enables data transmission of the terminal in an inactive state, and helps reduce terminal power consumption.

[0007] In a possible implementation, the indication information may be used to indicate that the terminal has a transmission requirement for one or more data packets when in an inactive state; for example, the indication information may be used to:

[0008] Instructing the terminal to transmit a data packet once;

[0009] Alternatively, indicating that the terminal needs to transmit a data packet a number of times greater than one and less than a maximum number of transmissions of the terminal in an inactive state;

[0010] Alternatively, the terminal is instructed to transmit data packets a number of times that is greater than or equal to a maximum number of transmissions of the terminal in an inactive state.

[0011] The terminal's need to transmit one or more data packets in an inactive state is reflected by indicating the number of transmission times. The base station can be informed of the range of data packets that need to be transmitted on the terminal side in an inactive state, so that the base station can flexibly make instructions and control the terminal's state transition, which is beneficial to the reasonable transmission of data packets and the control of terminal power consumption.

[0012] In a possible implementation, the indication information is used to indicate a desired state of the terminal when transmitting the one or more data packets, where the state includes an inactive state and a connected state; the indication information is used to:

[0013] Indicating that the terminal desires to transmit a data packet in an inactive state;

[0014] Alternatively, the terminal is instructed to transmit data packets in a connected state.

[0015] The transmission status indication reflects the terminal's expected data packet transmission status, so that the base station can flexibly make instructions and control the terminal's state transition, which is beneficial to the reasonable transmission of data packets and the control of terminal power consumption.

[0016] In a possible implementation, the indication information is used to indicate that the terminal has a transmission requirement for one or more data packets when in an inactive state, and the indication information is used to indicate a desired state of the terminal when transmitting the one or more data packets, where the state includes an inactive state and a connected state;

[0017] The instruction information is used to:

[0018] Indicating that the terminal needs to transmit a data packet once, and indicating that the terminal expects to transmit the data packet in an inactive state;

[0019] Alternatively, indicating that the terminal needs to transmit a data packet a number of times greater than one and less than a maximum number of transmissions of the terminal in an inactive state, and indicating that the terminal expects to transmit a data packet in an inactive state;

[0020] Alternatively, the terminal is indicated to need to transmit data packets a number of times greater than or equal to a maximum number of transmissions of the terminal in an inactive state, and the terminal is indicated to expect to transmit data packets in a connected state.

[0021] Through comprehensive instructions, the base station can be informed more clearly of the terminal side transmission requirements, making it easier for the base station to make decisions on terminal state transitions.

[0022] In a possible implementation, the indication information may be indicated by a preamble sent by the terminal to the network device;

[0023] Alternatively, the indication information may be indicated through message 3 (msg3) or message A (msgA) in the random access process.

[0024] By indicating through the existing preamble or msg3 or msgA, there is no need to construct a new message, which can better be compatible with existing standards and improve the convenience and effect of solution implementation.

[0025] In a possible implementation, the indication information is indicated by msg3 or msgA in the random access process, including:

[0026] The indication information is indicated by the connection resumption cause (resumeCause) value in msg3 or msgA during the random access process;

[0027] Alternatively, the indication information is indicated by the first bit in msg3 or msgA during the random access process;

[0028] Alternatively, the indication information is indicated through the first bit and the second bit in msg3 or msgA in the random access process.

[0029] By using the existing msg3 or msgA to carry indication information, compatibility with existing systems and standards is achieved, and there is no need to make major changes to the equipment software and hardware, which saves costs and facilitates implementation.

[0030] In a possible implementation, the method further includes:

[0031] The terminal obtains a maximum number of transmission times of a data packet in an inactive state.

[0032] By configuring the maximum number of transmissions, you can ensure that multiple data packet transmissions in the inactive state can achieve effective gains.

[0033] In a possible implementation, the maximum number of transmission times is configured by the network device and sent to the terminal; or

[0034] The terminal requests the network device to configure the maximum number of transmissions and sends the configuration to the terminal; or

[0035] The maximum number of transmission times is preconfigured in the system message.

[0036] In a possible implementation, the terminal sending the multiple data packets includes:

[0037] The terminal verifies validity of a first timing advance (TA) before sending a first data packet of the plurality of data packets;

[0038] If the first TA is verified to be valid, the terminal sends a first data packet of the multiple data packets through a first pre-configured resource configured by the network device;

[0039] When sending the first data packet, the terminal sends pre-configured resource request information to the network device, requesting the network device to allocate a second pre-configured resource for the terminal to send other data packets in the multiple data packets except the first data packet;

[0040] The terminal sends the other data packet through the first pre-configured resource and the second pre-configured resource, or the terminal sends the other data packet through the second pre-configured resource.

[0041] By sending the first data packet and the preconfigured resource request information through the first preconfigured resource, the second preconfigured resource can be acquired, and the transmission of multiple data packets in the inactive state can be achieved more flexibly and quickly. The terminal does not need to enter the connected state, thereby improving the efficiency of information interaction and data transmission and reducing the power consumption of the terminal.

[0045] The terminal sends the other data packets through the second pre-configured resources.

[0046] By sending the first data packet and the pre-configured resource request information through msg3 or msgA, the existing uplink authorization resources are reasonably utilized, the second pre-configured resources can be obtained, and then the transmission of multiple data packets in the inactive state can be realized. The terminal does not need to enter the connected state, nor does it need to perform random access interactions multiple times, thereby improving the efficiency of information interaction and data transmission and reducing the power consumption of the terminal.

[0206] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0207] The terms "including" and "having" and any variations thereof in the specification and claims of this application and the accompanying drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0208] In the Long Term Evolution (LTE) system and the New Radio (NR) system, random access can be completed between the base station and the terminal through the information exchange of four steps, msg1-msg4. For example, in a contention-based random access scenario, the following steps are included: msg1, the terminal sends a random access preamble; msg2, the base station sends a random access response message; msg3, the terminal sends msg3, the content of msg3 corresponds to several types of random access triggering events, for example, the content of msg3 is a Radio Resource Control (RRC) connection request for initial access, and the content of msg3 is an RRC connection reestablishment request when the connection is reestablished; msg4, the base station sends a contention resolution message. Thus, the random access process is completed.

[0209] In addition, in order to reduce the access delay of the terminal, a two-step random access method is proposed. The terminal sends a msgA message to the base station, and the base station responds with a msgB message. Only one such information exchange is required between the terminal and the base station to complete random access.

[0210] In the above and possible future random access scenarios, the terminal may be in the following states:

[0211] In the connected state, a radio resource control (RRC) connection is established between the terminal and a radio access network (RAN) device, such as a base station. While in the connected state, the terminal device stores its context information and can perform RAN-controlled cell handovers.

[0212] In the idle state, there is no RRC connection between the terminal device and the RAN device, and the terminal device and the RAN device no longer store context information. When the terminal device is in the idle state, the terminal device releases its own context information and can perform cell-based reselection.

[0213] In the inactive state, the terminal retains its own context information and can perform cell-based reselection operations. Meanwhile, the terminal's connection information, including its context information and core network connection, is stored in the anchor RAN device. While in the inactive state, the terminal retains the management area information configured by the anchor RAN device. The terminal needs to notify the anchor RAN device when it moves out of the management area corresponding to this management area information.

[0214] The inactive state may also be called the third state, light connection state, suspend state, etc.

[0215] When the terminal is in an inactive state, the RRC connection between the terminal and the RAN device can be restored through an RRC connection resume (Resume) message.

[0216] In the idle or inactive state, if a terminal has multiple data packets smaller than a preset threshold to transmit, the terminal may switch to a connected state for continuous transmission, or repeatedly perform a random access process (transmitting only one uplink and downlink data packet at a time). This results in cumbersome information exchange and high power consumption of the terminal. Therefore, the present application proposes a data transmission method to better achieve the transmission of multiple data packets.

[0217] For ease of explanation, the embodiments of the present invention are described using an LTE system or a NR system. The implementation methods in the embodiments of the present invention are also applicable to other existing communication systems and future higher-level communication systems such as 6G and 7G, and are not limited in any way in the embodiments of the present invention.

[0218] The data transmission method and device according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0219] Please refer to Figure 1 , is a schematic diagram of the architecture of a communication system in an embodiment of the present application. It may include network equipment and communication devices. For the sake of convenience, Figure 1 In the figure, the network device is taken as a base station 10 and the communication device is taken as a terminal 20 for illustration.

[0220] A network device may refer to a device in an access network that communicates with a terminal via a sector over the air interface. The network device can convert received air frames into and from Internet Protocol (IP) packets, acting as a router between the terminal device and the rest of the access network, including the IP network. The network device also coordinates the management of air interface attributes. For example, the network device can be a base station (Base Transceiver Station, BTS) in the Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA), a base station in Wideband Code Division Multiple Access (WCDMA), an evolved base station in LTE, or an access point (AP) in Wireless Local Area Networks (WLAN), a relay station, a vehicle-mounted device, a wearable device, and a network device in a future 5G network or a network device in a future evolved PLMN network, such as a base station that can be connected to a 5G core network device, a transmission and reception point (TRP), a centralized processing unit (CU), a distributed processing unit (DU), etc. This is not limited here.

[0221] Taking the network device as a base station as an example, the base station 10 can be an NR base station (gNB), an evolved NodeB (eNB for short), a NodeB (NB for short), a base station controller (BSC for short), a base transceiver station (BTS for short), a home base station (for example, Home evolved NodeB, or Home NodeB, HNB for short), a baseband unit (BBU for short), etc. It can also be referred to as a base station transceiver, a wireless base station, a wireless transceiver, a transceiver function, a base station subsystem (BSS for short) or some other appropriate terms by those skilled in the art. It is an entity on the network side for transmitting or receiving signals. In an embodiment of the present application, the base station 10 can receive indication information sent by the terminal, make decisions based on its own situation and the transmission information indicated by the terminal, and determine the mode and status of the terminal transmitting data. And allocate resources for sending data packets to the terminal.

[0222] The terminal 20 may also be referred to as user equipment (UE). It may be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it may also be deployed on water (such as on ships); or it may be deployed in the air (for example, on airplanes, balloons, and satellites). It may also be referred to as a user terminal, terminal equipment, access terminal equipment, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal equipment, mobile device, UE terminal equipment, mobile terminal, wireless communication equipment, UE agent, or UE device. The terminal may also be fixed or mobile. Its specific form can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a vehicle-mounted terminal device, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, a wearable terminal device, etc. It is an entity on the user side for receiving or transmitting signals. In the embodiment of the present application, the terminal 20 can send an indication message to the base station to inform the base station of the transmission information of sending one or more data packets when the terminal is in an inactive state, and request pre-configured resources from the base station to send one or more data packets. For the sake of simplicity of description, the embodiment of the present application only shows one terminal 20. In actual scenarios, the number of terminals 20 can be one or more. Some terminals can also serve as transfer devices to transfer messages for other terminals, and user groups can be formed between terminals, etc. The embodiment of the present application does not impose any restrictions.

[0223] See Figure 2 , Figure 2 A flowchart of a method for transmitting data provided in an embodiment of the present application includes the following steps:

[0224] S201: The terminal sends instruction information to the base station.

[0225] S202: The terminal sends the one or more data packets.

[0226] In a possible implementation manner, the indication information may be used to instruct the terminal to send transmission information of one or more data packets when in an inactive state.

[0227] The indication information may be used to indicate that the terminal has a transmission requirement for one or more data packets when in an inactive state; including:

[0228] Case 1-1: indicating that the terminal needs to transmit the data packet once;

[0229] Case 1-2: indicating that the number of times the terminal needs to transmit a data packet is greater than one and less than the maximum number of transmissions of the terminal in an inactive state;

[0230] Case 1-3: Indicates that the number of times the terminal needs to transmit data packets is greater than or equal to the maximum number of transmissions of the terminal in an inactive state.

[0231] When the number of transmissions is once, the base station can configure the terminal to complete the transmission of the data packet in an inactive state. The terminal can use the first pre-configured resources applied for by the terminal during the random access process, such as PUR resources or CG resources, or carry the data packet to be transmitted in msg3 through the random access process to complete the transmission of the data packet.

[0232] When the number of transmissions is greater than one and less than the maximum number of transmissions, the terminal can initiate a pre-configured resource request to the base station. After the base station allocates the second pre-configured resource to the terminal, it uses the first pre-configured resource (such as PUR resource or CG resource) and the second pre-configured resource (such as PUR resource or CG resource), or uses the first pre-configured resource or the second pre-configured resource to complete the transmission of the data packet.

[0233] When the number of transmissions exceeds the maximum number of transmissions in the inactive state, the base station can configure the terminal to enter the connected state and complete the data packet transmission in the connected state. This is because data packets cannot be transmitted an unlimited number of times in the inactive state. When the data packets are too large or too numerous, transmitting in the inactive state does not significantly improve the terminal's power consumption, so it can directly enter the connected state for transmission.

[0234] The terminal's need to transmit one or more data packets in an inactive state is reflected by indicating the number of transmission times. The base station can be informed of the range of data packets that need to be transmitted on the terminal side in an inactive state, so that the base station can flexibly make instructions and control the terminal's state transition, which is beneficial to the reasonable transmission of data packets and the control of terminal power consumption.

[0235] As for the maximum number of transmission times, before step S201, the terminal may first obtain the maximum number of transmission times of a data packet in an inactive state.

[0236] The maximum number of transmission times may be configured by the base station and sent to the terminal; or

[0237] The maximum number of transmission times may be configured by the terminal upon request of the base station and sent to the terminal; or

[0238] The maximum number of transmission times may be preconfigured in a system message.

[0239] In another possible implementation, the indication information is used to indicate a desired state of the terminal when transmitting the one or more data packets, where the state includes an inactive state and a connected state; and the indication information is used to:

[0240] Case 2-1: indicating that the terminal desires to perform data transmission in an inactive state;

[0241] Case 2-2: Indicating that the terminal desires to perform data transmission in a connected state.

[0242] When the terminal expects to transmit data packets in the inactive state, it indicates that the number of data packets to be transmitted is less than the maximum number of transmission times of the terminal in the inactive state. Therefore, the base station can configure the terminal to complete data packet transmission in the inactive state.

[0243] When the terminal expects to transmit data packets in the connected state, it indicates that the number of data packets to be transmitted is greater than or equal to the maximum number of transmissions. Therefore, the base station can configure the terminal to complete the data packet transmission in the connected state.

[0244] The transmission status indication is used to reflect the state of the inactive terminal when it expects to transmit data packets, so that the base station can flexibly make instructions and control the state transition of the terminal, which is beneficial to the reasonable transmission of data packets and the control of terminal power consumption.

[0245] In another possible implementation, the indication information is used to indicate that the terminal has a transmission requirement for one or more data packets when in an inactive state, and the indication information is used to indicate a desired state of the terminal when transmitting the one or more data packets, where the state includes an inactive state and a connected state.

[0246] The instruction information is used to:

[0247] Case 3-1: Indicates that the terminal needs to transmit a data packet once, and indicates that the terminal expects to transmit a data packet in an inactive state; at this time, the base station can configure the terminal to complete the transmission of the data packet in an inactive state, and the terminal can use the first pre-configured resources allocated by the network device when the last RRC connection is released, such as PUR resources or CG resources, or carry the data packet to be transmitted in msg3 through a random access process to complete the transmission of the data packet.

[0248] Case 3-2: Indicates that the number of times the terminal needs to transmit a data packet is greater than one and less than the maximum number of transmissions of the terminal in an inactive state, and indicates that the terminal expects to transmit a data packet in an inactive state; at this time, the terminal can initiate a pre-configured resource request to the base station, and after the base station allocates a second pre-configured resource to the terminal, use the first pre-configured resource (such as a PUR resource or a CG resource) and the second pre-configured resource, or use the first pre-configured resource or the second pre-configured resource to complete the transmission of the data packet.

[0249] Case 3-3: The number of times the terminal needs to transmit data packets is greater than or equal to the maximum number of transmissions in the inactive state, and the terminal desires to transmit data packets in the connected state. In this case, the base station may configure the terminal to transition to the connected state and complete the data packet transmission in the connected state.

[0250] Through comprehensive instructions, the base station can be informed more clearly of the terminal side transmission requirements, making it easier for the base station to make decisions on terminal state transitions.

[0251] It should be noted that the indication information sent by the terminal can be used as a reference for the base station when deciding the state transition of the terminal. The base station can also make a comprehensive decision based on any one or more of the following information:

[0252] Current resource usage, resource request priority or service priority of other terminals, channel status between the terminal, etc.

[0253] There are many ways to carry the indication information. For example, the indication information may be indicated by a preamble code sent by the terminal to the base station.

[0254] Alternatively, the indication information may be indicated through message 3 (msg3) or message A (msgA) in the random access process.

[0255] In the existing NR system, there are 64 preamble codes, which can be grouped, for example, into three groups, corresponding to the three situations they may indicate. For example, the 1st to 20th preamble codes are used as a group to indicate situation 1-1, 2-1, or 3-1; the 21st to 44th preamble codes are used to indicate situation 1-2 or 3-2, and the 45th to 64th preamble codes are used to indicate situation 1-3, 2-2, or 3-2.

[0256] In an embodiment of the present application, the terminal can inform the network side of its own transmission information when it is in an inactive state, which is beneficial for the network side to control the transmission status of the terminal and related resource configuration, realize data transmission of the terminal in an inactive state, and help reduce terminal power consumption.

[0257] When using msg3 or msgA for indication, two new values ​​for the resume cause can be added to the existing resume cause value: oneshort-data (indicating that there is a small data packet to be transmitted) and multishort-data (indicating that there are multiple small data packets to be transmitted). Figure 3 and Figure 4 ,in, Figure 3 A flowchart of a method for carrying indication information provided in an embodiment of the present application;

[0258] exist Figure 3 , the process of the four-step random access method is shown:

[0259] S301, the terminal sends a random access request (msg1) to the base station;

[0260] S302, the base station sends a random access response (msg2) to the terminal;

[0261] S303, the terminal sends a connection recovery request (msg3) to the base station;

[0262] It carries newly added connection recovery reason values ​​such as oneshort-data or multishot-data;

[0263] To indicate the transmission information of the inactive terminal to the base station.

[0264] S304, the base station sends a conflict resolution message (msg4) to the terminal.

[0265] In this way, the indication information can be carried through msg3 to inform the base station terminal of the transmission information.

[0266] Figure 4 A flowchart of another method for carrying indication information provided in an embodiment of the present application;

[0267] exist Figure 4 , the process of the two-step random access method is shown:

[0268] S401, the terminal sends msgA to the base station, carrying a random access preamble and an RRC connection recovery request message, etc., wherein the RRC connection recovery request message can carry a newly added connection recovery reason value such as oneshort-data or multishot-data; to indicate the transmission information of the inactive terminal to the base station.

[0269] S402: The base station sends msgB to the terminal.

[0270] In this way, the indication information can be carried through msg3 to inform the base station terminal of the transmission information.

[0271] In addition to using the existing reserved bits for indicating the connection recovery reason value to carry the indication information, the existing used bits for the connection recovery reason value can also be modified to carry the indication information, or the reserved bits in msg3 or msgA can be used to carry and indicate the indication information.

[0272] For example, the indication information may be indicated by the first bit in msg3 or msgA during the random access process;

[0273] Alternatively, the indication information may also be indicated by the first bit and the second bit in msg3 or msgA during the random access process.

[0274] When using the first bit for indication, for example, "1" can represent the need to transmit multiple data packets, while "0" can represent the need to transmit a single data packet; alternatively, "0" can represent the need to transmit multiple data packets, while "1" can represent the need to transmit a single data packet. Since a single bit can only indicate two situations, the aforementioned situations 1-1, 1-2, and 1-3 can be selected as needed. For example, in situation 1-3, where the maximum number of transmissions has been reached, this is a transmission in the connected state. If a transmission indication in the inactive state is required, "1" can be used to represent situation 1-2, while "0" can be used to represent situation 1-1. For another example, in situation 1-1, where only one transmission occurs, this is a single transmission with no state transition. If a transmission indication in a state transition is required, "1" can be used to represent situation 1-2, while "0" can be used to represent situation 1-3. The indication methods for situations 2-1, 2-2, 3-1, 3-2, and 3-3 are similar and will not be further described here.

[0275] When the first and second bits are used for indication:

[0276] For example, the first bit is 0 and the second bit is 1: it can indicate that there is one data packet to be transmitted, one data transmission is required, and the terminal expects to transmit in an inactive state (case 1-1 or 2-1 or 3-1).

[0277] The first bit is 1 and the second bit is 0: it means that the number of transmitted data packets is greater than 1 and less than the maximum number of transmissions. The number of required transmissions is the number of data packets, and the terminal expects to transmit in an inactive state (case 1-2 or 2-1 or 3-2).

[0278] The first bit is 1, and the second bit is 1: it indicates that the number of transmitted data packets is greater than or equal to the maximum number of transmissions, the number of transmissions required is the number of data packets, and the terminal expects to transmit in the connected state (case 1-3 or 2-2 or 3-3).

[0279] The first bit is 0 and the second bit is 0: it can be reserved.

[0280] It should be noted that the above bit values ​​are only for illustration. In actual use, they can be arbitrarily combined and configured as needed to indicate the various situations described above.

[0281] After the terminal completes sending the indication information, if there is a need to transmit multiple data packets, it can send a pre-configured resource request to the base station to obtain pre-configured resources for sending multiple data packets. Figure 5 and Figure 6 .

[0282] Figure 5 A flow chart of another method for transmitting data provided by an embodiment of the present application; the terminal can apply for a first pre-configured resource from the base station during the last RRC connection. When the base station releases the RRC connection, it configures the first pre-configured resource according to the terminal's request, so that the terminal can use the first pre-configured resource to transmit data once when it enters an inactive state after the connection is released. In order to achieve the transmission of multiple data packets, the terminal can apply for a second pre-configured resource from the network device, such as Figure 5 As shown, the following steps are included:

[0283] S501: A base station sends a radio resource control (RRC) release message to a terminal to configure a first pre-configured resource for the terminal, such as a PUR resource or a CG resource.

[0284] S502: The terminal verifies that the first TA is valid, that is, confirms uplink synchronization, and the current PUR resources or CG resources can be used.

[0285] S503, the terminal sends an RRC connection recovery request message to the base station, carrying a first data packet among multiple data packets and pre-configured resource request information, where the pre-configured resource request information is used to request the base station to allocate a second pre-configured resource for the terminal to send other data packets among the multiple data packets except the first data packet;

[0286] Among them, the second pre-configured resource can be a PUR resource or a CG resource.

[0287] S504: The base station sends an RRC connection release message to the terminal, and configures a second pre-configured resource for the terminal.

[0288] S505: The terminal uses the first preconfigured resource and the second preconfigured resource to transmit the other data packet, or uses the second preconfigured resource to transmit the other data packet.

[0289] In step S503, the pre-configured resource request information includes:

[0290] The number of pre-configured resources requested by the terminal and configuration information corresponding to each pre-configured resource, where the configuration information includes one or more of the following:

[0291] Transport block size, period for transmitting data packets using corresponding pre-configured resources, transmission timing, time offset, layer 1 (L1) confirmation information, hybrid automatic repeat process information, frequency allocation information, and demodulation reference signal.

[0292] Before step S503 , the terminal may first obtain the maximum preconfigured number of the preconfigured resources.

[0293] The maximum pre-configured number of the pre-configured resources may be configured by the base station and sent to the terminal; or

[0294] The maximum preconfigured number of the preconfigured resources is preconfigured in a system message.

[0295] The number of second preconfigured resources obtained by the terminal can be the same as or different from the number of data packets to be transmitted. The terminal can use the first preconfigured resources to transmit other data packets, use the second preconfigured resources to transmit other data packets, or use the first preconfigured resources and the second preconfigured resources to transmit data packets. When the number of configured resources is less than the number of data packets, these resources can be used to periodically transmit data packets. For example, two preconfigured resources can be used to transmit four data packets in two batches.

[0296] In step S504, the base station may also send a second TA to the terminal when configuring the second pre-configured resources. The second TA is used for uplink synchronization when the terminal uses the pre-configured resources to transmit data packets.

[0297] By sending the first data packet and the preconfigured resource request information through the first preconfigured resource, the second preconfigured resource can be acquired, and then the transmission of multiple data packets in the inactive state can be realized. The terminal does not need to enter the connected state, thereby improving the efficiency of information interaction and data transmission and reducing the power consumption of the terminal.

[0298] When the first TA is invalid, uplink synchronization cannot be achieved. Even if the terminal applies for the first pre-configured resource, it cannot be used. In this case, see Figure 6 , Figure 6 A flowchart of another method for transmitting data provided in an embodiment of the present application includes the following steps:

[0299] S601: The base station sends a radio resource control (RRC) release message to the terminal to configure a first pre-configured resource for the terminal, such as a PUR resource or a CG resource.

[0300] S602: The terminal verifies that the first TA is invalid, that is, uplink synchronization cannot be achieved, and the current PUR resources or CG resources cannot be used.

[0301] S603, the terminal sends msg1 to the base station;

[0302] S604, the base station sends msg2 to the terminal;

[0303] S605, the terminal sends msg3 to the base station;

[0304] MSG3 is sent through the uplink authorization resources (UL grant) allocated in MSG2, and MSG3 carries the first data packet among multiple data packets and pre-configuration resource request information. The pre-configuration resource request information is used to request the base station to allocate a second pre-configuration resource to the terminal for sending other data packets among the multiple data packets except the first data packet; the second pre-configuration resource can be a PUR resource or a CG resource.

[0305] S606: The base station sends an RRC connection release message to the terminal, and configures a second pre-configured resource for the terminal.

[0306] S607: The terminal uses the second pre-configured resource to transmit the other data packets.

[0307] The above steps S603-S605 correspond to msg1-msg3 in the four-step random access method, respectively. The method shown in the embodiment of the present application is also applicable to the scenario of the two-step random access method. For example, steps S603-S605 in the present application can be replaced with msgA in the two-step random access method, and msgA carries the first data packet of multiple data packets and the pre-configured resource request information. This completes the transmission of multiple data packets in the inactive state.

[0308] By sending the first data packet and the pre-configured resource request information through msg3 or msgA, the existing uplink authorization resources are reasonably utilized, the second pre-configured resources can be obtained, and then the transmission of multiple data packets in the inactive state can be realized. The terminal does not need to enter the connected state, nor does it need to perform random access interactions multiple times, thereby improving the efficiency of information interaction and data transmission and reducing the power consumption of the terminal.

[0309] In this embodiment, the terminal may proactively send pre-configured resource request information or other request information indicating the terminal's needs to the base station to request the base station to allocate the second pre-configured resource to the terminal.
